Abstract: Forkhead box (Fox) proteins characterized by a conserved winged-helix DNA binding domain
constitute a large family of transcription factors. Fox proteins regulate the gene transcription not only by
recruiting various coactivators like most transcription factors, some members of this family but also by binding
to the condensed chromosomes directly, which can remodel chromatin structure and generate a combinatorial
effect with other transcription factors to cause significant changes in expression. PI3K-Akt/PKBTGFβ-
Smad and MAP Kinase signal pathways regulate the activity of Fox proteins via phosphorylation reaction. The
diverse biological processes that Fox proteins influence, such as embryonic development, cell cycle regulation,
glucose and lipid metabolism, aging and immunoregulation, have also been covered in this article.
